Default Conversions and Converters

EclipseLink defines the following converter annotations and XML attributes (in addition to JPA-defined ones):

EclipseLink persistence provider searches the converter annotations in the following order:

  1. @Convert
  2. @Enumerated
  3. @Lob
  4. @Temporal
  5. Serialized (automatic)

You can define converters at the class, field and property level. You can specify EclipseLink converters on the following classes:

  • @Entity

For more information, see Section 8.1 "Entity" in the JPA Specification.

You can use EclipseLink converters with the following mappings:

If you specify a converter with any other type of mapping annotation, EclipseLink will throw an exception.
